MN 222 - Heraeus

Platinum Resistance Temperature Detector
MN 222
MN- series PRTDs are designed for large volume applications where long term stability, interchangeability and accuracy
over a large temperature range are vital. Typical applications are Automotive, White Goods, HVAC, Energy management,
Medical and Industrial equipment.

Application advice
1. To avoid shear forces on the connection area,
the connection wires may be neither split or bent.
The bending may only take place 3 mm after the
element, using a bending or splitting tool.
2. Other nominal values, lengths and temperature
coefficients on request.
3. Due to a production-caused oxide layer coating
the leads, soft-soldering is restricted.
Other tolerances, values of resistance are available
on request.
